Hi, As far as I'm concerned, it's a loopback bug.
Somebody appears to be trying to copy a 'struct file' in the routine 'loop_set_fd'. This will cause havoc in any and all filesystems that rely on f_ops->open() , f_ops->release() to maintain internal data. In this case, it's the file's RPC authorizations, that are getting garbage-collected from beneath you once the original struct file gets fput() at the end of the routine.
